Curve normalization for shape retrieval

Nacéra Laiche, Slimane Larabi, Farouk Ladraa, Abdelnour Khadraoui
2014 Signal processing. Image communication  
Finally, based on shape similarity of resulting curves, a shape similarity between an input shape and its reference model is defined. A two-step matching algorithm is proposed.  ...  In this paper, we propose a novel part-based approach for two dimensional (2-D) shape description and recognition.  ...  In the same way, the MAR is unique for each shape. Changing the orientation of a shape will change also the orientation of the MAR, but its dimensions remain unchanged.  ...
